[0058] In the specific implementation process, the specific implementation methods of the first spiral connection structure and the second spiral connection structure on the first mounting plate 601 and the second mounting plate 602 are basically the same as the reducer mounting plate in Example 1, so they are not repeated in this embodiment.

[0059] As a preferred embodiment, a mounting hole 605 connected to the cavity on the double swing bearing 6 is opened on the enclosure 603 and / or the sealing plate 604, so as to be used for quick assembly and disassembly of the first reducer 4 and the second reducer 5. The first reducer 4 and the second reducer 5 are installed and fixed inside the cavity without arranging an additional fixing structure outside the double swing bearing 6, thereby effectively reducing the space occupied by the double swing bearing 6.

At the same time, the two flat plates are also welded to the first mounting plate 601 and the sealing plate 604 to improve the structural stability. Among them, there are two connected notches on the arc-shaped plate and the sealing plate 604, which together form a larger mounting hole 605 to facilitate the rapid assembly and disassembly of the slewing mechanism.

[0062] refer to Figures 8 to 10The second embodiment of the enclosure 603 is shown. In this case, the enclosure 603 is an arc-shaped plate. The two straight edges of the enclosure 603 are respectively welded and fixed to the second mounting plate 602, and the two arc-shaped edges of the enclosure 603 are respectively welded and fixed to the first mounting plate 601 and the sealing plate 604. The mounting hole 605 is directly opened on the enclosure 603.

[0063] It is worth noting that in the specific application process, the sealing plate 604 is not limited to the use of Figure 6 , Figure 8 The embodiment shown may also adopt other special-shaped structures.

[0064] As a preferred embodiment, the enclosure 603 and / or the sealing plate 604 are also provided with observation holes and / or weight-reducing holes connected to the cavity, wherein the observation holes are used to observe the operation of the mechanism inside the cavity for timely maintenance, and the weight-reducing holes are mainly used for the dual-swivel mounting seat. It is worth noting that in the specific application process, multiple through holes 606 can be opened on the enclosure 603 and / or the sealing plate 604, which can be used as observation holes and weight-reducing holes at the same time.

[0065] In a specific implementation process, the first mounting plate 601 and the sealing plate 604 are parallel to each other, and the first mounting plate 601 and the second mounting plate 602 are both thicker than the enclosure plate 603 and the sealing plate 604 .

[0066] In the specific application process, the first reducer 4 and the second reducer 5 can also be replaced with a cylinder. It is only necessary to replace the reducer assembly structure on the reducer mounting plate, the first mounting plate 601, and the second mounting plate 602 with a cylinder assembly structure (such as a cylinder fixing barrel).
